Abstract (en)

[origin: WO2020254388A1] The invention relates to a vaporizer cartridge (10) as part of an inhaler, comprising a hollow body (15) with a continuous flow channel (16) and a storage tank (17) for storing liquid. The storage tank (17) has at least one access opening (18) to the flow channel (16), and a vaporizer unit (19) which extends over the entire access opening (18) is arranged in the region of each access opening (18), said vaporizer unit having a wick element (20) and a heating element (21), wherein the vaporizer unit (19) is designed to be liquid-permeable such that liquid can be conveyed out of the storage tank (17) in the direction of the flow channel (16) at least initially in a capillary manner by the vaporizer unit (19). The invention is characterized in that the wick element (20) is made of a plurality of granular grains (24) which form microchannels (23) by virtue of their packing and/or formation, said microchannels extending continuously from an inlet side ED of the wick element (20) to an outlet side AD of the wick element (20) in order to produce a fluidic connection between the storage tank (17) and the flow channel (16). An additional securing means (25) is provided which is designed and configured to hold the granular wick element (20) in place in the region of the access opening (18) so as to maintain the fluidic connection. The invention additionally relates to a corresponding inhaler (14).
